What is Linux?

Linux is an operating system intended for computers and other devices, such as servers, smartphones, tablets, and even bank teller systems. 

Just like Windows, from Microsoft, and Mac OS, from Apple, the Linux system is widely used and completely comprehensive. 

One of its major differentials is the presence of open source and editable code, which allows free distribution — after all, it was not created to be commercialized like Windows, for example.

With this feature, developers can work with all the code and create unique, customized solutions for each project. Excellent initiatives have already been developed on Linux, such as Ubuntu, Debian, Parrot OS, and CentOS. 

To understand how Linux works, you need to know what a kernel means. Simply put, the kernel is like the core of the operating system, which controls everything else — from hardware components to applications. 

But don't think that Linux is limited to the kernel! To work properly, the operating system needs to have its own applications, similar to those found in other more popular operating systems. 

In a quick comparison, Linux has its own text editor or Office suite (an example is Open Office, with spreadsheet, text, slides, and database editing), command prompts, file archivers, and more. Interesting, isn't it?

Why learn Linux?

Learning Linux can completely change your view of software and operating systems and open many new doors, both for IT professionals and those from other areas. 

The learning can be a differentiator on your resume, since many companies use the Linux system due to its low cost, good performance, and excellent data reliability. 

For professionals who work directly with Information Technology, in careers such as systems analysis and development, data security, networks, or even equipment maintenance, learning Linux can be a stepping stone. 

Learning to work with the system can place you in many relatively new areas, such as:

• cloud computing;
• mobile development;
• database administration.

These areas still have few qualified professionals and, consequently, offer high salaries and bonuses, but they require prior knowledge of Linux.

After all, this knowledge can be useful both for future opportunities to develop projects based on its kernel, as well as for professionals to understand the data structure and architecture of the system. 

Thus, it is clear how something simple, like learning Linux, can keep the professional more competitive and valued in the job market. Thinking about this should be a motivating factor to seek instruction in the field.

What are the applications of Linux?

We can observe the presence of Linux everywhere, not just on computers and cell phones, but also from your home router to the visual effects machines found in movies like Avatar and Titanic.

That's right! The applications of Linux are practically endless when it comes to equipment and interactive interfaces. 

Another interesting example of the system's application is in the American Maritime Defense Department: some submarines have Red Hat installed (an operating system based on Linux for corporate systems). 

Some bullet trains in Japan use the Linux system, as well as the European Organization for Nuclear Research.

First steps for programming on Linux

To start working with and getting familiar with the Linux system, it is important to have the operating system installed on your computer. About this, don't worry: Linux is free and has no annual license fees. 

Linux Distributions for Beginners

To make the learning curve easier, you should know that there are various distributions, or distros, available for beginners to adapt more quickly. 

Distributions are nothing more than sets of software based on Linux, usually free and open source. 

To be viable in this case, distros need to be easy to install and configure, as well as have a simple interface and an accessible support community. 

Some examples of simple distributions are:

• ZorinOS;
• Ubuntu Linux;
• Kubuntu;
• Linux Mint
• Pop!_OS;
• openSUSE
• Debian and many others.

How to Install Linux

To install Linux on your computer, you need to pay close attention so that there are no errors during the process. 

You can find the desired Linux distribution for free on download websites.

The first step, without a doubt, is to choose your favorite distribution, among those mentioned above, and download it for free in ISO format, which can be burned to either a CD, as was common in the past, or a USB drive. 

After installation, you need to boot, or start, the operating system. As soon as the computer boots, you need to configure the BIOS to choose your preferred storage system. 

Finally, simply start the operating system installation and make some simple configurations such as time adjustments, date, layout, and user login. 

Keep in mind that before installing on a computer that was already in use, it is wise to back up all important files and photos. 

Practicing Programming on Linux

If you still don't feel confident enough to install and use Linux as your only operating system, know that it is entirely possible to use it and another one on the same computer. 

The "magic" happens through dual boot or a Virtual Machine. The first method requires the user to choose, each time the computer boots, which operating system will be used. 

This technique is effective because it doesn't overload the computer's physical system, since each operating system is run at a time, ensuring that the processor and RAM memory, for example, are 100% utilized.

The second option, on the other hand, consists of installing another operating system in an overlaid manner. In other words, they work as emulators. 

This is an excellent option for those who want to perform tests safely, since actions taken in the emulator do not affect the main operating system.

Just choose your preferred method and start tinkering!

Best Resources for Beginners
